GRAINING-TOOL.

Specification of Letters Patent.

Patented Aug. 5,1913.

Application led December 14, 19.12. .Serial No. 736,731.

10 graining tools, the object of the invention being to provide an improved tool which may be used by any one of average intelligence to grain in imitation of a large numsber of different kinds of wood.

A further object is to provide a graining tool of the character described which may be manufactured and sold at an extremely low price, and which is adapted to be used in connection with a soft thin rag and capable 20 of a wide range of usefulness in all sorts of graining work.

lVith these and other objects in view, the invention consists in certain novel features of const-ruction and combinations and ar- 25 rangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in side elevation illustrating my Fig. 2 is a similar view of the opposite side of the tool. Fig. 3 is a view in section on the line 3 8 of Fig. l, and Fig. 4 is a perspective view of one of the rubber strips.

My improved grainer tool comprises a board l which may be made of any desired material. Heavy pasteboard will answer the purpose, but of course, the invention is not limited to the particular material of 40 which this board is made. At opposite sides of the board l at one edge, two rubber strips 2 are secured and at the other longitudinal edge, a rubber strip 2 and a brush 3 are secured. The brush 3 comprises a series of vacant spaces between clusters of such bristles, and their arrangement is purposely irregular. The bristles are conned against the board l by a strip 4, and while I have illustrated small tacks or nails 5 as a securing means for the several strips 2 and the brush 3, it is to be understood that I also employ glue or other adhesive to rmly connect the parts. Around the outside of the board and partially inclos- 5 ing the strips 2, is a covering sheet 6 which is secured by means of a suitable adhesive.

This strip 6, at one side, is slightly wider than at the other side, so that it hides the strip l as clearly shown in Fig. 3.

It wil-l be noted that all of the strips `2, at their outer edges, lie flush with the outer -edges of the board l, ai, d furthermore, all of said strips 2 are provided with a plurality of angular or inclined recesses 7 forming between them tongues S. It will be further noted that each of these strips has a differently arranged set of tongues 8, some of the tongues `being narrower than others, and in some of the strips, it is desirable that the tongues should be of different widths at their contacting ends, while in others a more uniform arrangement may be had. These rubber strips 2 are adapted to rub over the paint with an interposed soft thin rag between them and the paint, and when in the hands of a skilful user, the various grains may be imitated by the rubbing action on the paint. The brush 8 is used in a like manner with a soft thin rag covering the same, and by varying the pressure on the tool, and varying the stroke, practically any well known wood may be imitated by the tool.

As above stated the recesses 7 are at an angle or incline. This is especially advantageous in giving to the wood a grain which runs diagonally of the wood and does not interfere with the straight graining although most of the grains of the wood are more or less at an angle to the longitudinal edge. In any event, the inclination of these recesses permits the tool to form a more perfect imitation of irregular graining than would be the case if they were at right angles to the edge.

The brush is especially adapted for graining imitation walnut, cherry, or cypress, but of course I do not limit myself to the particular use of the several features of my improved tool, and various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A graining tool comprising a board,

strips secured to said board at its edges, said strips having recesses therein, and a brush secured to said board at one edge having an irregular arrangement or' bristles projecting beyond the edge of the board7 substantially as described.

2. A graining tool Comprising Ia board, strips secured to said board at its edges, said strips having recesses therein, a brush secured to said board at one edge having an irregular arrangement of bristles projecting beyond the edge of the board, and a covering strip secured around the board and over portions of said brush and strips, substantially as described.

In testimony whereof l have signed my name to this specication in the presence oi two subscribing Witnesses.
